Determination of the Dark Matter (DM) density at the solar position is critical to direct and indirect dark matter searches. Additionally, it is important to make this determination with as few assumptions as possible, as results from direct detection searches are used to explore a wide variety of theoretical models, and hidden astrophysical assumptions could bias theoretical searches. Here we pre

Accelerated expansion of our universe, as evidenced by Supernovae Ia (SNeIa), Cosmic Microwave Background (CMB) radiation anisotropies, Large Scale Structure (LSS) and X-ray experiments, is well documented in literature. A missing energy component, also known as Dark Energy (DE) with negative pressure, is widely considered by scientists as the responsible of this accelerated expansion. DE model, s

In the context of Twin Higgs models, the mirroring of the Standard Model strong sector suggests that a twin baryon with mass around 5 GeV is a natural dark matter candidate once a twin baryon number asymmetry comparable to the SM asymmetry is generated. We study a natural implementation of Asymmetric Dark Matter in such models and its phenomenology.

Under rather generic assumptions, we show that in the asymmetric dark matter (ADM) scenario, the sign of the B-L asymmetry stored in the dark matter sector and the standard model sector are always the same. One particularly striking consequence of this result is that, when the dark matter decays or annihilates in the present universe, the resulting final state always involves an anti-neutrino. As

Cartan has proposed a model of number systems given by octonions and a pair of 4 dimensional vector system. Octonions contains 2 quaternions or a pair of Dirac particles
and by the transformation G_{23}, particle-antiparticle transformation occurs, and by the transformations G_{12},G_{123},G_{13} and G_{132}, supersymmetric transformation occur.
We extend the model to the system in which quark,

It is known that after Affleck-Dine baryogenesis, spatial inhomogeneities of Affleck-Dine field grow into non-topological solitons called Q-balls. In gauge mediated SUSY breaking models, sufficiently large Q-balls with baryon charge are stable while Q-balls with lepton charge can always decay into leptons. For a Q-ball that carries nonzero $B$ and $L$ charges, the difference between the baryonic c

In this talk, I will describe complementarity of direct detection and collider searches for Higgs portal DM models, and show that it is essential to work in renormalizable and gauge invariant DM models for collider searches (both the invisible Higgs decay and the monojet (or dijet) + missing ET). In particular we derive the bounds on new physics scale within a UV model, and show that it is complet

For over a decade the XENON Collaboration has been a pioneer in the field of dark matter direct detection. The collaboration has achieved world-leading sensitivities in WIMP-nucleon interactions using liquid xenon time projection chambers (TPCs), first with the XENON10 and later with the XENON100 experiments. This year the next phase, XENON1T, will begin data-taking with an unprecedented one ton f

CALET (Calorimetric Electron Telescope), launched to the ISS in August, directly measures the electron+positron cosmic rays flux up to 20 TeV.
With its proton rejection capability of 1 : 10^5 and an aperture of 1200 cm^2 sr, it will provide good statistics even well above one TeV, while also featuring an energy resolution of 2%, which allows it to detect fine structures in the spectrum. Such stru

Dwarf spheroidal satellites of the Milky Way are a prime target for dark matter indirect searches. E.g., upper limits on gamma-ray fluxes in their directions, obtained with the Fermi Large Area Telescope, have been recently used to update constraints on weakly interacting massive particles (WIMPs), excluding pair annihilating cross sections at the level of WIMP thermal relic cross sections for WIM

An 800kg liquid xenon detector (XMASS) was constructed at Kamioka Observatory, Japan in 2010. XMASS can be made the low background region in center of detector by shield of the liquid xenon which eliminates the background in detector surface. A commissioning run was conducted from November 2010 to June 2012. We found the unexpected background in detector surface. In order to reduce these backgr

The framework of non-relativistic effective field theory (NREFT) aims to generalise the standard analysis of direct detection experiments, which is typically framed in terms of spin-dependent (SD) and spin-independent (SI) interactions. I will show that a number of these more general NREFT operators lead to distinctive new directional signatures, such as prominent ring-like features in the directi

We point out that domain wall formation is a more common phenomenon in the Axiverse than previously thought. Level crossing could take place if there is a mixing between axions, and if some of the axions acquire a non-zero mass through non-perturbative effects as the corresponding gauge interactions become strong. The axion potential changes significantly during the level crossing, which affects t

Probing the thermal WIMP paradigm for Dark Matter is one of the primary goals of the high energy physics community. To study the interplay of the LHC with direct and indirect detection experiments, it is necessary to study benchmark WIMP models. I will do so by adding to the Standard Model an electroweak multiplet, which is arguably the simplest way to realise such a study. Besides that, these DM

We consider a simple extension of the Higgs sector in a Higgs portal dark matter where a real scalar is a candidate for dark matter in the present Universe. This Higgs sector extension allows that its dark matter annihilation suitably explains the observed excess of the gamma-ray flux from the Galactic Center. We identify the parameter region of the model that can fit the gamma-ray excess and sati

We reconsider the model of Minimal Dark Matter (a fermionic, hypercharge-less quintuplet of the EW interactions) and precisely compute its gamma ray signals. We compare them with a number of gamma-ray probes: the galactic halo diffuse measurements, the galactic center line searches and recent dwarf galaxies observations. We find that the original minimal model, whose mass is fixed at 9.4 TeV by th

I will present results on the analysis of gamma-ray emission from the recently discovered dwarf galaxy Reticulum II. Using Fermi-LAT data and a suite of background models we quantify the probability that the observed gamma-ray emission is due to background. Taking into account trials factors, we find emission p-values in the range between 9.8x10^-5 and 9.7x10^-3 and conclude that Reticulum II h

The recent claim that gamma-ray excess exists in FERMI data has triggerred many interesting discussions. Here we propose several simple higgs-portal dark matter models for explaining the excess. We also compare various channels using global fit.

There is significant astrophysical uncertainty in the interpretation of data from dark matter direct detection experiments, due to the poorly known dark matter distribution at the position of the Sun. I will discuss the local dark matter density and velocity distribution of Milky Way-like galaxies obtained from the high-resolution EAGLE hydrodynamical simulations. To make reliable predictions for

The one-point function (i.e., the isotropic flux distribution) is a complementary method to (anisotropic) two-point correlations in searches for a gamma-ray dark matter annihilation signature. Using analytical models of structure formation and dark matter halo properties, we compute the gamma-ray flux distribution due to annihilations in extragalactic dark matter halos, as it would be observed by

An updated analysis on the mu --> e + gamma was performed in a new class of non-sterile electroweak scale right-handed neutrino models with a A_4 symmetry in the neutrino sector. This class of models provide an interesting link between charged lepton flavor violating processes to the physics of neutrino sector. Constraints from the current limit and projected sensitivity from MEG experiment are st

The nature of dark matter (DM) is an open issue of modern physics. Cosmological considerations and observational evidences indicate a behaviour beyond the Standard Model for optimal dark matter particle candidates. The non-baryonic dark matter is compatible with a gas of cold and weakly interacting massive particles (WIMPs) expected to have a mass in the range between O(10)GeV and O(100)TeV. Indir

Dark matter can excite the xenon isotopes 129Xe and 131Xe through a spin dependent interaction. The excited isotopes quickly decay giving a 40 keV and 80 keV photon, respectively. This signal is very distinct from the usual signal from elastically scattering dark matter and, if discovered, would provide clear evidence against the usual spin independent interaction. I discuss the prospects of disco

One of the most promising way to detect dark matter is to look for its annihilation or decay products among cosmic-rays. Recently, more and more interesting results are reported by measurements of cosmic-rays from various kinds of targets such as the milky way galaxy, dwarf spheroidal galaxies, cluster galaxies, etc. Among them, dwarf spheroidal galaxy is one of the nearest, dark matter dominated

In the standard model (SM), Higgs lepton-flavor-violating (LFV) decay is absent and thus it is a good probe to new physics. In this article we study a type of new physics that could lead to large Higgs LFV decay, i.e., leptophlic dark matter (DM) specified by the particle property of DM (a Majorana fermion) and DM-SM mediators (scalar leptons). Different than other similar setups, here we introduc

In my talk I will review the case of scalar dark matter model in which case the dark matter candidate couples to the Standard Model (SM) fermions through Yukawa interactions involving a new vector-like fermion. The latter models are already know to give rise to particularly interesting gamma ray signals when the Yukawa coupling is restricted to leptons. In my talk, I will present our latest result

We are searching the Singlet Majorana dark matter (DM) by using constraints from relic density, colliders (LHC and LEP), DM direct detection, and DM indirect detection. By the means of effective field theory (EFT), we write down several kinds of higher dimensional operators and show the allowed parameter space by current experiments in DM mass and cut-off scale plane. Furthermore, we also try to e

Using gamma-ray data from the Fermi Large Area Telescope, various groups have identified an excess emission in the inner Galaxy centred around energies of a few GeV. This excess resembles remarkably well a signal from dark matter annihilation. One of the most plausible astrophysical interpretations is in terms of the combined emission from an undetected population of dim gamma-ray sources. In part

The halo dark matter (DM) can be gravitationally captured by the Sun. For
self-interacting DM (SIDM), we show that the number of DM trapped inside
the Sun remains unsuppressed even if the DM-nucleon cross section is
negligible. We consider a SIDM model where *U*(1) gauge symmetry is introduced
to account for the DM self-interaction. Such a model naturally leads to
isospin violation for DM-nuc

Whether or not an exotic component, as the fugitive Dark Matter, contributes to the observed high-energy CR fluxes, is one of the most important open problem in Cosmology. Charged CRs play a key role in this context, since Weakly Interacting Massive Particle annihilations or decays can be a copious source of antimatter in our Galaxy, and the local CR fluxes from conventional astrophysical sources

Observations of the ARCADE-2 and other telescopes have reported a significant isotropic emission spanning from 22 MHz to 10 GHz. The intensity of this signal significantly exceeds the expected contribution from known astrophysical sources, and the distribution of the signal is suggested to be unusually smooth compared to emission which traces large scale structure. In this talk, we investigate the

One of the good candidates for cold dark matter is the lightest Kaluza-Klein particle (LKP),which produce electrons and positrons by pair annihilation in the Galactic halo. The directions of electrons and positrons are randomized by the Galactic magnetic field, and the energy is reduced by some energy loss mechanisms, when the charged particles propagate in the Universe.
We calculate the ob

There is a striking evidence for a roughly spherical-symmetric diffuse gamma-ray signal peaked in the Galactic Center (GC) region, extended up to several degrees off the GC.

The arguably most simple model for WIMP dark matter is a scalar singlet that couples to the Standard Model sector via the Higgs portal. It is a simple example for beyond-the-Standard Model (BSM) physics, and can be tested with collider, direct, indirect and cosmological probes. In this talk, I will present the first analysis results for the scalar singlet dark matter model that we obtained with
